YouTube Videos on Nutrition and Dental Caries: Content Analysis.

Background: Dental caries is the most common health condition worldwide, and nutrition and dental caries have a strong interconnected relationship. Foods and eating behaviors can be both harmful (eg, sugar) and healthful (eg, meal spacing) for dental caries. YouTube is a popular source for the public to access information.

Comparing the perceptions and opinions of the 2007 and 2019 Canada's food guides among parents of young children.

Background: The Canada's Food Guide (CFG) is recognized as the most prominent authoritative guideline for healthy eating in Canada. In 2019, Health Canada released the latest iteration of the CFG with substantial changes to its messaging and format from the previous 2007 CFG.

Objective: This study compared the awareness, use, knowledge, and opinions of the 2007 and 2019 CFGs among parents with children aged 18 months to 5 years who are participants in a family-based intervention trial, the Guelph Family Health Study.

Dietary Change during Pregnancy and Women's Reasons for Change.

Women often make dietary changes during pregnancy; however, dietary modifications and reasons for changes are not well studied. We aimed to describe the dietary changes made during pregnancy, describe reasons for dietary changes, and determine what changes aligned with recommendations. Pregnant women ( = 379) recruited to the Alberta Pregnancy Outcomes and Nutrition (APrON) study in 2009/2010 completed a questionnaire in which they described dietary changes made during pregnancy and reasons for those changes.

Changes in dietary and physical activity risk factors for type 2 diabetes in Alberta youth between 2005 and 2008.

Objective: Unhealthy dietary and physical inactivity patterns inspired many initiatives promoting healthy youth and healthy schools in Alberta between 2005 and 2008. The purpose of this study was to examine differences in the prevalence of lifestyle risk factors for type 2 diabetes (T2D) between two province-wide samples of Alberta adolescents (2005 and 2008).

Methods: The dietary and physical activity (PA) patterns of Alberta youth were assessed in two cross-sectional studies of grade 7-10 students, one in 2005 (n=4936) and one in 2008 (n=5091), using a validated web-survey.

Anthropometric and dietary predictors of insulin sensitivity in 10- to 14-year-old boys and girls.

The high prevalence of pediatric obesity has made preventing chronic diseases through healthy lifestyle behaviours a priority within pediatrics. Examining the association between diet and insulin sensitivity (IS) in youth may provide important insights for tailoring preventative dietary interventions. The objective of this study was to explore the associations among anthropometry, diet, and IS in 10- to 14-year-olds.

Geography influences dietary intake, physical activity and weight status of adolescents.

Purpose. The purpose of this study was to assess rural and urban differences in the dietary intakes, physical activity levels and weight status of a large sample of Canadian youth in both 2005 and 2008. Materials and Methods.

Adolescent weight status and related behavioural factors: web survey of physical activity and nutrition.

Purpose. To identify whether non-overweight students were different from their overweight or obese peers with respect to diet, suboptimal meal behaviours, and physical activity using a self-administered web-based survey. Methods.

Associations between the perceived presence of vending machines and food and beverage logos in schools and adolescents' diet and weight status.

Objective: The increasing prevalence of obesity among youth has elicited calls for schools to become more active in promoting healthy weight. The present study examined associations between various aspects of school food environments (specifically the availability of snack- and beverage-vending machines and the presence of snack and beverage logos) and students' weight status, as well as potential influences of indices of diet and food behaviours.

Design: A cross-sectional, self-administered web-based survey.

Dietary patterns associated with glycemic index and glycemic load among Alberta adolescents.

The purpose of this study was to assess the dietary glycemic index (GI) and glycemic load (GL) of adolescents, based on a Web-based 24-h recall, and to investigate dietary predictors of GI and GL. In addition, the relationship between GI and GL and weight status was examined. A Web-based 24-h recall was completed by 4936 adolescents, aged 9-17 years; macronutrient and food group intakes were assessed using the ESHA Food Processor, the Canadian Nutrient File, and Canada's Food Guide.

Diet quality, nutrition and physical activity among adolescents: the Web-SPAN (Web-Survey of Physical Activity and Nutrition) project.

Objective: To assess the overall diet quality of a sample of adolescents living in Alberta, Canada, and evaluate whether diet quality, nutrient intakes, meal behaviours (i.e. meal skipping and consuming meals away from home) and physical activity are related.
